PATENT FREDERICK GUILD, OF CANTON, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO GEORGE F. HALL, OF BOSTON, MASSACHUSETTS.

WINDOW AND DOOR PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 227,355, dated May 11,1880.

Application filed March 13, 1880. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK GUILD, a citizen of the United States, residing at Ganton, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Window and Door Protectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in window and door protectors or safety-guards, for the purpose of preventing burglars from entering; and it consists of vertically-adjustable slotted bars that are caused to rise upward by means of suitable weights attached to cords that are guided over pulleys in the upper part of the window-frame, the said cords, after passing over their pulleys, being secured to the upper bar.

In combination with the vertically-adjustable slotted bars, I use a pair of oscillating notched locking bars, one on each side of the window or door frame, that serve as vertical guides for the horizontal slotted bars during their vertical adjustment, and also to lock and confine the horizontal bars in position when in use as a guard or protector. The said notched locking-bars are pivoted in bearings at top and bottom, and are caused to remain in an unlocked position, by means of the influence of coiled or other springs, until acted upon by inclines on a detachable window-sill or horizontal board, that cause the locking-bars to turn around their axis a partial revolution, whereby the horizontal bars are firmly confined in their proper positions in front of the window or door.

By looking the detachable window'sill in position, by means of a suitable lock and key, 45 it will be seen that the window or door is socurely guarded and protected against the entrance of burglars. A pocket or receptacle is arranged below the window-sill for the reception of the sliding bars when not required for use. Suitable chains, links, or cords connect the several horizontal guards or bars, so as to keep them at a proper distance from each other.

I wish to state that the vertically-adjustable guards may be operated from above or below, and by means of weights or springs, without departing from the spirit of my invention.

On the .accompanying drawings, Figure 1 represents an interior front elevation of my invention as applied to a window-frame, and representi n g the guards in their raised position. Fig. 2 also represents an interior front elevation of myinvention, showing the guards down and resting in their pocket. Fig. 3 represents a longitudinal section on the line A B, shown in Fig. l; and Fig. 4 represents a crosssection on the line O D, also shown in Fig. 1. Fig. 5 represents a plan view of the detached sill-piece.

Similar letters indicate similar parts \vher- 7o ever they occur on the difl'erent parts of the drawings.

a a. is the frame of the window, and I) is the lower pocketor receptacle for the adjustable guards when not in use. 0 c are the oscillating locking-bars, having circular ends 0 c at top and bottom, and resting in bearings in the frame a, in which they may turn. 0 c are lockin g notches or recesses on the locking-bars c c, as shown. d d are springs for the purpose of automatically holding the locking-bars c c in an unlocked position, as shown in Fig. 2, so as to enable the horizontal guards or protectors e e e e to slide freely up or down in raising and lowering them. v 8

The guards e e are each provided in their outer ends with slot-holes c c, as shown in Fig. 4, through which the locking-bars c c are inserted, and by which means the guards c e are guided in their vertical adjustment. 0

f fare stays or ropes connecting the several guards e e 0, as shown.

g g are the weights attached to the cords h h, running over the guide-pulleys it, as shown, the upper ends of the cords h h being attached 9 5 to the uppermost guard c, as shown.

It is a detachable sill-piece or board provided with inclines Z l, which latter serve the purpose of turning the locking-bars c c a par tial revolution around their axis, and thus ef- 10o feet the rigid locking of each of the guards e e to the notched or recessed places c. c on the locking-bars c 0, as shown in Figs. 1 and 3.

m represents a suitable lock on the pocket or receptacle b, for the purpose of securely locking the detachable sill-piece k in place when the guards e e are in their upper position, as represented in Fig. 1.

n is a latch for the purpose of holding down the guards e 0 within the pocket bwhen not in use.

To raise the guards to the position shown in Fig. 1, it is only necessary to remove the sill-piece 7c and to unfasten the latch n, when the bars 0 0 e 6 will automatically be raised to the position shown in Fig. l by the action of the weights 9 g acting on their cords h hand pulleys 1? i, as described.

To firmly lock the guards e e in position. it is only necessary to replace the silLpiecek to its original position, when its inclinesl I come in contact with the oscillating locking-bars c c, and thus turn the latter a partial revolution around their axis in a locking position, as shown in Figs. 1 and 3. The sill-piece 7c is then locked by means of the look m, as de' scribed, and in this position the guards e 6 cannotv be raised or lowered until the sill-piece 7c isremoved.

To lower the guards c 6 all that isrequired to do is to unlockthe sill-piece it; from the pocket I) and to remove the former, whenthe locking-bars c 0 are instantly turned around their axis by the action of the springs dd, so as to-allow the slotted ends a e of the guards e e to slide easily downward on the notched lockingbars 00. By taking hold of the guards e 6 they can easily be pulled down and placed one over another within the pocket I), and there confined by means of the fastening n until I needed for use again. The sill-piece 7c is then replaced in its original position.

0 o are a pair of narrow boards hinged, by means of their hinges 0 0, to the frame a, which boards can be swung to the position indicated by dotted lines in Fig. 4, so as to conceal the lockingbars 0 0, and thus make a neat ,andfinished appearance of the whole.

Having thus fully described the nature, construction, and operation of my invention, I

wish to secure by Letters Patent, and claim 1.. The herein-described window or door proslotted guards c e e c, the oscillating notched locking-bars c c c c", springs 11 d, detachable sill-piece 7a, with its projections Z Z, weights g g, cords h h, and pulleys t i, as and for the purpose described.

4. In combination, the vertically-adj ustable slottedguards e 0 cc, the oscillating notched locking-bars c c c c", the-detachable sill-piece k, and pocket or receptacle b, as and for the purpose set forth.

In testimony whereof I have affixed my signature in prcsenceof two witnesses.

FREDERICK GUILD.
